The Intel C++ compiler throws an internal error when trying to build clang 15:

Hi,

Thank you for posting in Intel Communities.

We have tried with icx(C),icpx(CXX) compiler while building and we did not face any issues. Could you please try with the below commands and let us know the results.

git clone --depth=1 --branch llvmorg-15.0.0 https://github.com/llvm/llvm-project.git
mkdir build
cd build
cmake -DLLVM_ENABLE_PROJECTS=clang -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles" -D CMAKE_C_COMPILER=icx -D CMAKE_CXX_COMPILER=icpx ../llvm-project/llvm
make

Thanks and Regards,

I am not using the oneAPI compiler icpx but the legacy version icpc. I haven't tried icx/icpx yet but will do that.
